For a long period of time, widely used in the production of components of an effective insecticide rotenone is mainly from the genus Derris root extract, collect rotenone from the root to dig down to two meters deep, the human cost of not only high-cost and easy caused by soil erosion, many of the genus Derris production has stopped growing, leading to the market with rotenone as the main active ingredient of the biological pesticide manufacturers shortage of raw material sources.

相当长一段时间，在生产上广泛使用的有效杀虫成分鱼藤酮主要是从鱼藤属植物中的根部提取，采集鱼藤酮的根要挖掘至地下达两米深，不仅人力成本耗费高，而且容易造成水土流失，不少鱼藤属植物的产区已经停止种植，导致市场上以鱼藤酮为主要活性成分的生物农药制造企业原料来源短缺。

MJ and geraniol all could inhibit the PLBs growth. With the raising of their concentration , their inhibition inhanced. MJ 100mol L-1 could inhance the accumulation of effective components in PLBs, but geraniol at different concentration inhibited the accumulation of effective components in PLBs.

MJ和牻牛儿醇均会抑制拟原球茎的生长，随着浓度的增加，这种抑制作用增强。100μmol/L~(-1)MJ可以提高拟原球茎中有效成分的积累，而不同浓度的牻牛儿醇都抑制了有效成分的积累。

The nutrients,such as V A,V E,V C,amino acid,phospholipids,glucose oxidase DNA and RNA,in the pollen of Rosa Xanthina and Hemerocallis minor are studied and the result is that the nutrients especially of V A,V E,V C,EAA,DNA and RNA are rich and the proportion is good.

通过对黄刺莓和金针花粉的DNA ，RNA ，磷脂，葡萄糖氧化酶，氨基酸，VA，VE 和VC 等重要营养成分的测定，发现这两种花粉的营养成分丰富，配比良好，特别是VA，VE，VC 和必需氨基酸的质量比较高，RNA和DNA的质量比也较高。

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.

扫描电镜观察到液氮脆断的人工泪小管内部成分分布均匀，内外壁表面平整，冷冻干燥的人工泪小管断口呈凝胶态的互穿网络结构。3 组不同成分的人工泪小管在PBS 溶液中浸泡30 min 后均快速吸水溶胀，外径扩大100%～ 120%，内径扩大20%～ 30%，并且随胶原含量增高，溶胀速度增快，平衡溶胀率增大。3 组人工泪小管在37℃含2 mg/mL 溶菌酶的PBS 液中浸泡1 个月后，表面有部分细小絮状物，管口开裂，管壁变薄，透明度增加。

The planting condition and the nutritious component of samphire were studied after its introduction into yancheng, and the results showed that its main nutritious component had no diversification though the planting condition and the component content had changed slightly due to the altering of climate, the soil and so on. Further more, several nutriment's content had been increased.

通过比较北美海蓬子和盐城海蓬子在生长条件和营养成分的差异，发现北美海蓬子引种盐城滩涂后，虽然由于气候、土壤等条件发生了变化使其栽培条件和各营养成分的含量发生了一定的变化，但是其主要营养分组成却没有变化，而且改良后的品种某些营养素的含量得到了提高。

It was shown that the main compositions of the stones were uric acid dehydrate and ammonium urate, so we derived the mechanism of stone formation from the metabolic process of the two stone compositions, meanwhile, we raised some advices on the diagnosis and the treatment of the disease.

目前已知，这种结石的成分主要是二水尿酸和尿酸铵，所以本文通过这两种成分的代谢过程来逆向推导这种特殊结石形成的过程，同时也提出一些相关的诊断和治疗上的建议。

对于未确定的种类，数量仅仅是成分的比例规格的一个参考量（例如，通过有局部，有成分，或者有包含关系），例如，一群人中有60％的女人是人（量＝100），有其中的一部分（女人数量＝60）。

The aroma components of pumelo peel tea and white tea were studied in this paper, and the scenting effect of pumelo peel tea was compared and evaluated;both the style of aroma in white tea and the changes of the aroma components of white tea during preservation were discussed.

本文在研究了柚子皮茶和白茶香气成分的基础上，探讨了4种柚子皮茶的窨制效果；分析了白茶的香气特征和在存放过程中白茶香气成分的变化。

Because you can split a 256-level QAM signal into a 16-level ASK (amplitude-shift-keying) signal for the in-phase component and a 16-level ASK for the quadrature component, a symmetrical approach is feasible.

因为将256级QAM信号分离成同相成分的16级ASK信号和求积成分的16级ASK，对称的方法是可行的。

The purpose was to accumulate data preli minarilyfor learning chemical ingredients and pharmacological efficacy of celery and provideexperimental basis for studying and screening ingredients with pharmacological effect further.

为了解芹菜的化学成分和药理功效作初步的资料积累和进一步展开对芹菜中具有药理作用的成分的研究和筛选提供试验依据。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
